Windows 8.1 launches in UK on 17th October, 2013

Just received the news from Microsoft's PR that Windows 8.1 will launch in New Zealand at 12.00am on the 18th October (so midday on the 17th in the UK) and roll out worldwide via a free update in the Windows Store. So yes, you will need a Microsoft Account to get this. Having tried the preview, I reckon it will definitely be worth the upgrade, as it fixes many broken features and improves usability, particularly for non-touchscreen devices.
